Model: HELIXORA SC-88. Simulation seed: 485632. Category: Industrial Machines. Publisher: MySimulator.uk.

Industrial compressed air powers workshops, production lines, pneumatic actuators, packaging equipment and many automated processes. The screw compressor is one of the most recognizable machines in this field, yet its essential mechanism is normally sealed inside a heavy casting. HELIXORA SC-88 changes the viewing angle. This interactive 3D engineering lab takes a fictional, educational oil-injected compressor and separates it into 150 named, selectable mechanical parts. You can watch the parts move away from the assembly, examine their roles, bring them back into alignment, and run the main mechanisms without dealing with a pressurized machine.

The scene is not a photograph or an animated video. The browser renders separate 3D surfaces for the frame, compressor casing, male and female screw rotors, timing gears, shaft bearings, electric motor, cooling system, oil separator, pressure controls and service fasteners. Each part has metadata, an original installed position and an assembly parent. This makes the experience suitable for mechanical curiosity, engineering education, introductory compressor training and interactive visualization practice.

Why the two screw rotors matter

At the centre of the machine are two helically shaped rotors inside a closely fitting casing. One rotor is driven by the motor; its mate is synchronized by the rotor geometry or timing system, depending on the compressor design. Air enters at the suction end, occupies spaces between the rotor lobes and housing, travels axially along the rotating screws, and is discharged when the trapped volume becomes smaller. The changing volume raises the air pressure. There is no conventional reciprocating piston and cylinder carrying out one compression stroke at a time.

The SC-88 model illustrates a four-lobe driving rotor and a six-lobe mating rotor. To represent their relative angular speeds, the animation applies the idealized relationship in which the six-lobe member rotates at two-thirds of the angular speed of the four-lobe member, in the opposite direction. This is a demonstrative kinematic model rather than a contact-solved computational fluid dynamics study. Real screw profiles are carefully engineered for sealing, displacement, strength, lubrication and thermodynamic efficiency; the displayed swept surfaces are educational approximations and not production cutting-tool paths.

What oil injection achieves

An oil-injected compressor routes lubricating liquid to the airend for several purposes. Oil can remove heat produced during compression, help seal clearance gaps and lubricate moving contact regions. After leaving the airend, the compressed air and oil mixture must be separated. The model includes a separator vessel and coalescing element, oil filter, scavenge pump, distribution manifold, injection nozzles, return paths and a finned cooler.

Follow the copper-coloured pipes from the discharge side to the separator and then toward the filter and cooler. These paths communicate the functional concept: oil needs filtration, thermal management and a route back to the machine. Pipe routing is schematic, not an approved pressure-circuit diagram. Real machines also incorporate minimum-pressure valves, thermostatic valves, control logic, level management and numerous safeguards that differ across manufacturers. The simulation intentionally avoids supplying operational procedures for actual pressure equipment.

Nine systems, 150 individually selectable parts

The skid and frame represent the mechanical foundation. Structural rails, crossmembers, pedestals and isolation mounts transmit loads to the base while damping vibration. The airend and casing surround the rotors and define the suction and discharge passages. Split shell sections reveal the working volume when viewed in X-Ray mode, while end flanges and reinforcement ribs show how housings are assembled.

The helical rotor train contains both screw elements, their long shafts, collars and synchronization gears. The precision-bearing system includes outer races, inner races, rolling elements and shaft seals. Bearings play a critical role because a small change in rotor alignment can alter internal clearances and cause loss of efficiency or damage. The display emphasizes the mechanical constraint without pretending to simulate bearing friction, elastic deformation or thermal growth.

The power drive contains a stylized 11 kW induction motor, motor cooling fins, fan, shaft, flexible coupling and mount. The oil circuit conveys the main separation and circulation features. The heat-rejection system includes a cooler matrix, fin elements and a driven axial fan. The intake and controls group represents a modulating butterfly valve, actuator, pressure instrument, thermal probe, relief valve and control enclosure. Finally, individually named fasteners provide educational assembly steps: even a small service bolt has its own selectable geometry and mounted state.

Five ways to explode the machine

Select Explode and drag the distance slider from zero to 100 percent. At zero the parts return to their authored assembly transforms. At full separation you can identify shapes that disappear behind the casing in normal view. Full explosion moves the parts outward according to their individual position and deterministic spacing. Layered explosion groups elements vertically, helping reveal how multiple manufacturing layers occupy the same assembly. Subsystem explosion lifts the selected mechanical family while leaving other systems in contextual positions. Technical explosion spreads components into a presentation-oriented layout and adds labels. Cinematic explosion staggers the departure of components to create a fluid reveal sequence.

All five methods use calculated transforms rather than accumulating repeated offsets onto prior frames. This distinction matters. A common fault in interactive exploded views is component drift after multiple play and reverse operations. Here, each frame starts with the saved assembly coordinate and adds one mathematically determined separation vector. Returning the slider to zero therefore restores the original position rather than an approximation of the last animated position.

Manual reassembly is different from reverse playback

A press of the reverse playback button can put every part back in place, but it does not test the user's understanding. Manual assembly does. Select Assemble to initialize a component staging layout. The base remains installed, while supported parts are detached and separated into individual staging locations. Use the assembly explorer to select a part. You can drag it in the 3D viewport, adjust its position with the arrow keys, and correct the rotational key using the bracket keys. After alignment, the magnetic snap action checks its distance to the authored mounting anchor and its rotational error.

Dependency checks prevent an invalid assembly order. For example, a rotor shaft depends on the rotor to which it belongs, while an airend cover depends on the supporting housing bulkhead. A child cannot be installed until its parent is present. Free Assembly lets you select any eligible part; Guided Assembly identifies the next valid candidate; Challenge mode removes the easy prompts and awards points for successful placements. Stage Part can bring an eligible part close to its mounting anchor, but the final alignment and snap validation still matter.

These constraints are educational simplifications. A complete industrial maintenance workflow would require lockout, lifting, fastening torque, clearances, lubrication procedures, and inspection steps beyond the scope of an interactive browser experience. Never infer actual assembly safety procedures from the game.

Operate the compressor kinematics

Move to Operate and start the motor. The male helical rotor turns while the female rotor counter-rotates with an idealized 4:6 relationship. Drive-related coupling elements rotate in response to the shaft animation. The cooling fan and oil pump pinion respond to their corresponding settings. Adjusting the inlet value changes the depicted butterfly-valve angle, providing a visual connection between inlet modulation and machine control. The oil-flow setting is a demonstration control rather than a predicted measured flow rate.

The speed slider changes the motion of the system. Low rotor speed is particularly useful for observing the relative rotation of the lobes and the timing gears. Higher speed conveys the continuous nature of rotary compression but does not attempt to synthesize accurate sound, vibration or flow pulsation. A browser-based educational scene is appropriate for recognizing kinematic relationships, not verifying shaft stresses, mass balancing, pressure pulses or bearing fatigue.

X-Ray, inspection and camera navigation

When the machine is assembled, the casing conceals many of the most important parts. X-Ray mode makes the housing panels partially transparent so the internal rotor train remains visible without physically removing them. Use the part inspector to isolate one component, hide it, reveal all hidden elements, read its metadata or focus the camera on its centre. The searchable assembly tree lets you locate parts by name, ID, material or description.

The camera supports mouse orbit, pan and wheel zoom, with front, rear, side, top and isometric presets. Touch interaction includes one-finger rotation and two-finger pan and pinch zoom. The viewport can be expanded to fullscreen where the browser permits it. Learning progress may be marked for individual parts; assembly and lesson data are stored locally in the browser rather than transmitted to a remote account. These browser-local saves are convenient but not permanent across cleared storage, private sessions or different devices.

Materials, lighting and mechanical appearance

The metal colours distinguish structural steel, aluminium alloys, chrome finishes, brass, copper and cast housings. Rubber mounts, insulation-style black parts, glass-like fittings and painted control pieces provide contrasting surfaces. The full Three.js project uses physically based materials, dedicated directional lighting and real geometry exported as a GLB model. The no-dependency static package also includes an independent WebGL2 renderer with lighting calculations and a software Canvas2D fallback for environments that cannot create a WebGL context.

To keep loading manageable, repeated mechanical features reuse procedural descriptions, while the final scene remains a genuine 150-object mesh hierarchy. The exported model has 26,636 triangles in its authored arrangement. This level of detail supports interactive identification and mechanical study without pretending to be a manufacturing CAD assembly with drawings, tolerances, seals and certified parts. Rendering performance depends on device hardware, browser implementation, pixel density and which renderer is active.

Technical learning versus engineering specifications

HELIXORA SC-88 is an original fictional training machine, not a product offered by an industrial manufacturer. The displayed reference data—11 kW illustrative motor input, 1.2 cubic metres per minute illustrative displacement at 7 bar, and 2,400 rpm example male-rotor rating—serve only to make the mechanical discussion concrete. They are not a compressor selection chart. The 4:6 lobe relationship is a simplified synchronization rule. Geometry dimensions are visualization coordinates, not a metric production drawing, and pressure-vessel details are schematic.

For real compressor work, engineers need manufacturer manuals, rated pressure data, flow tests, safety standards, lubrication specifications, material certifications, installation drawings, thermal calculations and service training. This simulation helps learners recognize which components exist and how they relate, but it must not be used as an instruction for building or operating pressurized equipment.

Start exploring on MySimulator.uk

Begin in Explore mode and rotate the machine to identify the motor and compressor housing. Open X-Ray to see the helical pair. Move to Explode and compare the full, layered and technical arrangements. In Assemble mode, stage an eligible part and try to restore its intended alignment; the completion indicator advances only when parts pass the dependency and magnetic-snap checks. Finally, start the simplified rotating mechanisms to connect the static parts to their roles in a working air compressor.

Because the downloadable simulation is static, it can be served by an ordinary web host without a login system, external API keys or a dedicated server. Educators can embed it alongside a lesson, while enthusiasts can return to study the same mechanical model and track their inspected components locally. For deeper mechanical design work, use a certified drawing or a qualified engineering simulation tool rather than treating this educational interactive as a validated design.
